Annotated Information
Gene Symbol
- Os10g0558900 <=> RL14,OsRL14
Function
- RL14 encode a 2OG-Fe (II) oxygenase of unknown function.
- RL14 gene affects water transport in leaves by affecting the composition of the secondary cell wall.
- This change in water transport results in water deficiency, which is the major reason for the abnormal shape of the bulliform cells.
Phenotypic analysis
- rl14 mutant plants had incurved leaves because of the shrinkage of bulliform cells on the adaxial side.
- In addition, rl14 mutant plants displayed smaller stomatal complexes and decreased transpiration rates, as compared with the wild type. Defective development could be rescued functionally by the expression of wild-type RL14.
Expression
- RL14 was transcribed in sclerenchymatous cells in leaves that remained wrapped inside the sheath.
- In mature leaves, RL14 accumulated mainly in the mesophyll cells that surround the vasculature.
- Expression of genes related to secondary cell wall formation was affected in rl14-1 mutants, and cellulose and lignin content were altered in rl14-1 leaves.
Evolution
- The RL14 gene was mapped first to an interval between the simple sequence repeat (SSR) markers RM3123 and RM1162 on the long arm of chromosome 10.
- Finally, the RL14 locus was mapped to a 24.5-kb DNA region between the InDel marker SID2 and SSR marker SW24 on a single bacterial artificial chromosome, AC079874.
- RL14 was related most closely to members of the 2OG-Fe (II) oxygenase family from rice and sorghum.
- Orthologous of RL14 was identified in other species, such as maize, Arabidopsis, Papaver somniferum, Vitis spp and Ricinus communis.
